Setting your booking reminder timing

Under Settings > Notifications, you can choose how many hours before the appointment a reminder is sent. Enter anywhere from 1 to 168 hours (7 days) — the default is 24 hours.

Reminders follow the same channel priority as the booking confirmation (Kakao Alimtalk → SMS → Email).

Bookings made close to the reminder window don't get a separate reminder

If a booking itself comes in closer to the appointment than your reminder window, no separate reminder is sent — the confirmation message you already sent covers that role.

Example: with the reminder set to "24 hours before", if a client books online at 5pm today for a 4pm appointment tomorrow (only 23 hours away, inside the 24-hour window), no separate reminder goes out. The confirmation message sent at booking time already includes the date and time, so the client sees it there instead. A client who books a week in advance, on the other hand, still gets a reminder exactly 24 hours before their appointment as normal.

If a client says they never got a reminder

First check when the booking was made relative to your reminder window — if it was made inside that window, the behaviour above is expected. Otherwise, check that the client's contact details (phone/email) are entered correctly, and that you haven't run out of notification credits.
